Downloading a photograph taken on-line and seeing that the Modified Date is completely different from the date it was taken, has the photograph been edited?

When you have no idea, yesterday the web neighborhood had a “chilling” when Tran Thanh launched pictures of financial institution statements from the donation of donors to charity. Additionally on this information stream, there are some doubts that when downloading the above pictures, the EXIF ​​test reveals the date and time and the taking pictures gadget, however in comparison with the Modified Date within the Properties part of the photograph, it’s displayed. one other time, proves this has been edited/reassembled?

So what’s the fact, is EXIF ​​and Modified Date associated?

First we have to perceive the definition of the next:

EXIF: is an acronym for Exchangeable Picture File Format, or may be referred to as a convertable picture file format). When a photograph is taken with a digital digicam or cellphone, the JPEG picture file (or HEIC or DNG…) is recorded to the reminiscence card/reminiscence of the digicam. And on this picture file, EXIF ​​can also be included.

Based mostly on EXIF, we are able to know the date and time the photograph was taken, customized parameters within the digicam similar to ISO, aperture, shutter velocity, flash is on, the place the photograph was taken (if accessible). GPS location tag permission). So, briefly, EXIF ​​is probably the most “true” factor as a result of it reveals precisely what’s recorded proper on the taking pictures gadget.

Created và Modified Date: That is how the pc (or cellphone) working system data the standing of a file or folder. For instance, whenever you copy an image from a reminiscence card to your laptop at 1pm, your laptop will acknowledge the file as “Created” to the onerous drive at 1pm. Once you open the view, or transfer it to a different folder, the whole lot is modified to a brand new partition on the onerous drive and now the Modified Date may even change, which doesn’t essentially imply that you’ve got edited the picture. by post-production software program.

In different phrases, Created and Modified Date are like a diary that data the journey that file “circles” and is counted solely because it was written to your laptop’s onerous drive/reminiscence.

And I attempted to make use of a photograph of myself, taken at 14:19 on Monday (September 6, 2021) for example. I first uploaded it to Google Drive round 12:00 midday right now (September 8, 2021) and the photograph has not been edited in any respect. Now the time has been modified (create and modify) in keeping with Google’s cloud onerous drive, so it ought to show right now’s date and time. After I shared the hyperlink for my youthful brother to obtain to my laptop, this image was created and modified as soon as extra in keeping with the timeline recorded on my brother’s laptop.

If that is repeated, my brother continues to make use of that photograph to add to his personal Google Drive and obtain it from there, the outcome will likely be that my laptop will report a totally new time. Modified Date instantly modified to 10:40pm final evening (September 7, 2021), so the place did this time come from?

Re-download now Modified time is 07/09 at 10:40 PM??? The place is that this time???

Jokingly in keeping with the films, the timeline has been damaged as a result of formation of many alternative “universes”. And tracing the Created and Modified timelines of a file that has gone by means of many ends is like in search of an entity floating someplace within the timeline of the multiverse. The time displayed in Properties right now could also be right, could also be fallacious, could leap earlier than the entire day of water. The way in which to report the time of every system, every working system is completely different.

In line with OrganizingPhotos.internet, the date deviation has many causes:

– The date and time setting on the gadget is wrong

– The date and time on the seize gadget is reset whenever you change the battery (this solely applies to the digicam)

– If utilizing a number of cameras, the time and data could also be fallacious when syncing.

– Once you take a printed photograph, put it within the scanner to change into a digital picture file within the laptop, then the time can also be recorded in keeping with when the image was created from the scanner.

– And at last, whenever you obtain and extract that photograph from anyplace (even the Web) the time will likely be incorrect (metadata inside EXIF ​​has been tampered with and even eliminated).

In brief, if you wish to know when a photograph was taken, take a look at EXIF ​​for probably the most correct outcomes. Nevertheless, do not examine the EXIF ​​in opposition to the Modified Date and suppose it is edited, particularly when the photograph has been loaded throughout completely different units and storage areas, like Multiverse of Insanity.
